为了探讨体育锻炼对普通女青年代谢特征的影响 ,对体育系和生物系女生 70 %最大耗氧量 (70 % V· O2 max)强度下跑台运动 2 0 m in前后的血乳酸 (BL A)、血糖 (BG)、乳酸脱氢酶(L DH)、异柠檬酸脱氢酶 (ICDH)活性进行比较。结论 :在相同的相对负荷应激下 ,体能较高者生理反应较小 ,无氧供能比重较低 ,运动后 BL A较低 ,静息及恒负荷后 ,2组间血糖、血清酶活性均无明显差异 ,说明用这些指标衡量机能水平不敏感。 In order to investigate the effect of physical exercise on the metabolic characteristics of ordinary young women, the blood lactate (BL A) before and after the treadmill exercise at 70% V · O2 max ), Blood glucose (BG), lactate dehydrogenase (L DH) and isocitrate dehydrogenase (ICDH) activity were compared. CONCLUSIONS: Under the same relative stress, the patients with higher physical fitness have lower physiological response, lower specific oxygen-free energy, and lower BLA after exercise. After resting and constant load, the blood glucose and serum enzyme activities No significant difference, indicating that the use of these indicators to measure the level of performance is not sensitive.
